In an optical projection system using a mercury-vapour discharge lamp, the amount of energy emitted has maxima corresponding to mercury emission lines and so to reduce these maxima and provide a move uniform energy distribution, a filter is employed which comprises a transparent support coated with at least one light reflecting layer having an optical thickness of 5#/4 where # is in the yellow-green part of the spectrum. # may be 5600 Š Œ 80 Š so that the optical thickness is 7000 A + 100 Š. The filter thus has not only a 3rd order reflection peak at approximately 5600 A but also 2nd and 4th order reflection peaks at about 9300 A and 4200 A respectively. In a projection system the filter may be placed where the beam is parallel i.e. after the condenser lenses and before the film or transparency so that the latter is protected from the reflected energy. In an example a 1 mm. transparent plate is coated on one side with a layer of zinc sulphide, magnesium fluoride, and zinc sulphide respectively each having an optical thickness of 7000 A and similar layers, only of an optical thickness of 3600 A/4, may be coated on the other side to provide an additional 1st order reflection peak in the violet region of the spectrum. The bandwidths of the reflection peaks may be reduced by having 5 layers instead of 3.
